Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed April 4, 1912. Serial No. 688,424.

To all whom it may concern:

Be it known that I, HENRY LANGE, a citizen of the United States,residing at Quincy, in the county of Adams and State of Illinois, haveinvented certain new and useful Improvements in Stoves; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to stoves, and it more particularly relates to acombined opener and fastener for a stove door or closure.

An object of the invention is to provide, in connection with an ash-pitdoor or the like, means for opening said door by the simple manipulationof a handle, whereby the door may also be partially or entirely closed,said opening and closing means being mounted independently of the door.

A still further object is to provide a device of the character describedwhich may be operated either by hand or by the foot of an operator.

A still further object is to provide frictional means, resilientlymounted, for holding the door actuating element in adjust-ed position.

Other objects and advantages will be hereinafter made clearly apparentin the specification and claims.

In the accompanying drawings, which are made a part of this application,Figure 1 is a perspective view of the complete device, and, Fig. 2 is avertical sectional view through the central portion thereof.

Referring to the drawings, in which similar reference numerals designatecoresponding parts throughout the several views, an ash-pit door isdesignated by the numeral 5, being pivotally secured to the body of thestove at 6, in the usual manner. The door 5 is provided With lug 7, andwith the usual knob 8, by which it may be opened, closed and fastened.The door 5 is provided with an opening 9, through which a shaker shaft10 may be easily operated, in the usual manner, when said opening is notclosed. The opening 9 is provided with a closure 11, which is pivoted tothe lug 7 by pins 12, and is adapted to be swung in a vertical plane,into closed position, as in Fig. 1, or into open position, as shown infull lines and in dotted lines, in Fig. 2. This closure is provided withan arouate cam-surface 13, which coacts with an arm 14, for closing theclosure 11, in a manner hereinafter described.

The actuator consists of an L-shaped member, of which the arm 14 formsthe vertical portion, and a handle 15 constitutes the horizontal portionwhen the actuator is in its normal position, in which the closure 11 1sclosed. The actuator is pivoted to the door 5 at a point approximatelyunder the vertical center of the closure 11, and is adapted to be swungthrough an arc of approximately 90", on a pivot pin 16 extendingtherethrough. The pin 16 is provided with a head 17 against which isseated a helical spring 18. A housing 19 incloses the spring 18 and aportion of the pin 16 and head 17 said housing being seated upon theactuator and being provided with a shoulder 20 adjacent to its bottom,against which is seated the spring 18. It will ,be seen that the spring18, acting against the head 17 and the shoulder 20, presses the housing19 into frictional contact with the actuator and thereby holds it in anyof its several adjusted positions.

The actuator is provided with a convexed cam-surface 21 which willhereafter be known as the opener.

In operation, considering the device in its normal position, as in Fig.1; if the handle 15 be moved downwardly until the arm 14 passes thelower right portion of the camsurface 13, the closure 11 will be openedby contact of the opener 21 with the inclined surface 22 of the closure11. At this stage of the operation the portion 23 of the closure restsupon the portion 24 of the arm 14 and supports the closure; so that, asthe handle 15 is moved farther, the arm 14 is further lowered, therebyallowing the closure 11 to open wider until it has reached the positionshown in broken lines in Fig. 2. Obviously, when it is desired to againclose or partially close the closure 11, this may be accomplished byswinging the handle rightward and upward, so that the portion 24 of thearm 14 bears upwardly on the portion 22 of the closure 11, and the arm14 comes into contact with the cam-surface 18, and co-acts with thespring 20, for holding the closure firmly and resiliently against theseat 25 of the door 5.

It will be seen that the mechanism described is capable of attaining theforegoing objects, and in a thoroughly practical and eflicient manner.

I do not limit my invention to the exact details of construction,combination and arrangement of parts, as described and illustrated, butmy invention may only be limited by a reasonable interpretation of thefollowing claims.

What I claim as new is:

1. In a stove having an opening therein, a closure for the, openingpivoted to the stove on a plane below the opening and adapted to beswung in a vertical plane, an actuator pivoted to the stove below theclosure and adapted to be swung into operative relation with the closurefor opening and closing the latter.

2. In a stove having an opening therein, a closure for the openingpivoted to the stove and having a cam-surface, an actufor holding thehousing in frictional contact with the actuator whereby the latter maybe securely held in different adjusted positions, for the purposespecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
